HORSEPUCKYThe other Bob said:The simple answer is no.
You can't change the total weight on the front,rear or sides of the car without physicaly moving weight(ballast or moving the battery to the trunk etc)
You can change the corner weight (diagonal) with adjustable coil-overs though.
Here's a link that can help http://www.grassrootsmotorsports.com/cornerweight.html
You know what Bob, I don't give a rat's ass what GRM says or Rebco says. BTW, my understanding is that adjusting weight jackers and adjusting coilovers are not the same thing.The other Bob said:I beg to differ George...read the last paragraph and insert the words "Front, Rear, Leftside or Rightside"
Like it say's "you can turn the jack screws all day and it won't change"
Stafford? Way cool! Do the Supermodifieds still come there? I grew up in Rochester, NY and 20 years ago used to go to Oswego all the time. Sometime I hope to get back to Rochester in the summer so I can go to another race at Oswego. God, I love that place. I'm not much into circle track racers anymore, but I absolutely adore Supermodifieds and really like Midgets. BTW, have you seen this month's issue of Racecar Engineering? They have an article on the ISMA Supers.The other Bob said:Yeah George,I've done plenty of this myself on my own cars and alot of customers & friends cars,from street cars to Nascar pavement modifieds and everything in between.
I sponsor an S/K Modified @ Stafford Motor Speedway
Oh God, I'm so sorry to hear about the brain tumor. I'm so glad the outcome. Godspeed.The other Bob said:#16 Davidson Foods/Performance Centers
Driven by Wayne Bellefleur (sadly sidelined for 02 due to a brain tumor but, after the surgery he's finally been given the green light from the doctors for 03!!!! )
Yeah, I know Hartford has plenty of SR20 powered cars around there. I met a bunch of the guys there a couple of years ago when I met up with them at Acceleration Pluss. I drove Craig Damashi's SE-R at the 01 SE-R convention. Without a doubt it was the best rotating SE-R I've ever driven, including our racecar.The other Bob said:And yes "Performance Centers" is my shop located here in East Hartford Connecticut
Stop by if you're ever "in the neighborhood"
We seem to have a Sentra/NX2000/240sx thing goin' on here lately...about 10 SR20de/sr20det powered cars
I'm 95% sure they did. I don't have the data here so I cannot confirm it. But, I am pretty sure I double checked that because of the aforementioned Will Cagle article and I wanted to check that the info I was getting from others to the contrary was correct.The other Bob said:Yes I'm sure it affected all 4 corners but, the "weight percentages" (total front, total leftside etc.)for the front,rear,left or right didn't change.
I guess that's possible. The shift wasn't terribly large as I recall. But, like you, I think the effect of fuel slosh would be minimal.The other Bob said:If they did you may want to have your scales checked.
The only possibility would be fuel load shifting in the fuel cell/gas tank but of coarse, the amount from that would be minimal I'm sure.
Thanks for the explanation. I never knew how a weight jacker worked.The other Bob said:Well you're partially correct...They are 2 different things.
They do the same job with the same results though.
"Weight jackers" are a threaded rod that is fixed to the chassis where the end sits on the spring to adjust it, while a "coil-over" is a nut that's threads on a shock or strut that adjusts the spring.
They both adjust load on the spring & chassis hight.
What's his name? I followed those cars through the late 70s and basically knew a lot of the names in the northeast. I would bet your dad did know Will Cagle. They were of the same era. Cagle stopped racing in the mid to late 70s. I think I saw him race once. He was the hot shoe of the DIRT circuit when it was just starting out.The other Bob said:'Ya know what ? I think my dad knew this guy,my father raced dirt track modifieds from the late 50's to late 70's.
Hehe. That's cool that he's still racing.The other Bob said:'til he made the switch to pavement...still racing too at 66 yrs old, albeit in a "Legends" car now that he's "retired"
I've been to so many dirt tracks in New England when I was a kid my mom thought I'd never come clean...haha
Hey, mine's even longer.The other Bob said:Sorry for the long post
Heck yeah, I know most all those guys. Jay Hassinger, Matt Niaura, and a few others. Makes me wonder if you weren't there when we all went to Hooters a couple of years ago when I was there.The other Bob said:You know Craig Damshi? (aka phsyco)...yeah I know most all of the "Nissan guys"...good people.
Bob Legere too...friends from long ago.
I'll bet there's about 6 or 8 guys that frequent this board and hang out at my shop.
Sounds about right.The other Bob said:Seems as if the current plan from all the guys that hang out @ the shop is to turbocharge every Nissan in the area...so far it's working
Sounds very familiar.The other Bob said:My fathers name Bob Leach (same as mine
Started racing the #16 then the 3, M3, 103, then drove for Arnold Fluery in # 52 for a few years and drove for Roy Messick then back to driving his own cars...oh hell he's been racing longer than I am old! and I'm 40.
He's built & sold more cars than I can count
Hehe. I know what you mean about the sleep. I have too many things going on in my head (and they ain't no damned sugar plums ). I'm trying to get new products out of my head, on the drawing board or into CAD, get prototypes done, and get them into production. The problem is, the ideas keep coming faster than I can get things done.The other Bob said:Back to the subject,I'm going to scale a car tomorrow and I'll post the results then...I need sleep!
Have you ever corner weighted a car?mranlet said:No, the weight distribution of the car remains the same (probabally 50/50 if you have a skyline or 240sx), as no parts are changing positions within the car.
Static weight distribution is a different issue from load transfer.mranlet said:You can probabaly visualize this if you think about the car being so low in the front, for instance, and the back being jacked up so that there is almost no load on the rear wheels. This would give the same effect as brake dive, with the back end acting as if it were lighter, when in reality it still weighs the same with the weight merely being loaded on to the front of the car instead of the rear...
